An article exchange method and device based on a block chain

Abstract

The embodiment of the invention discloses an article exchange method and device based on a block chain. The method may include: receiving a transaction request associated with an item from a transaction initiator, the transaction request including identification information of the item; Based on the identification information of the article, acquiring article information of the article from the blockchain account book; Assessing the item based on the item information to generate an assessed value, and broadcasting the generated assessed value to the blockchain network; Generating a reference value of the item based on the received evaluation value information, the evaluation value information including a plurality of evaluation values from the plurality of blockchain nodes; Participating in the consensus of the block chain network on the reference value; And based on a consensus result, storing the reference value in the blockchain account book. According to the method disclosed by theembodiment of the invention, the information disclosure degree and the article value transparency of the article exchange market can be enhanced, and tedious steps of article exchange are simplified.

Description

technical field [0001] The present disclosure generally relates to information processing technology, and more specifically, relates to a method, device, and corresponding computer-readable storage medium for item exchange based on blockchain. Background technique [0002] Blockchain (Block Chain) technology is based on a decentralized peer-to-peer network, which combines cryptography principles with consensus mechanisms to ensure the coherence and continuity of data in distributed blockchain nodes, and to achieve non-tamperable and Features such as unforgeability, thus creating a distributed trust system that is private, efficient and secure. [0003] In the industry of items (for example, second-hand items (such as second-hand cars, second-hand real estate, etc.)) exchange (for example, the exchange of items and vouchers (such as points, monetary assets, etc.)), information asymmetry is a major obstacle to the development of the industry . A transaction initiator (eg, a ...

Problems solved by technology

The opacity of market information makes it easy for both the transaction initiator and the target transaction party to be at a disadvantage in the transaction process, resulting in low activity in the exchange of items in the market

In addition, the quality of the items depends entirely on the information provided by the centralized service provider (for example, an intermediary platform) (for example, passing information to customers through advertising, etc., the information may contain false data) as a basis, and the service provider Often in a monopoly position, once a problem occurs, it is difficult to assign responsibility to the party whose interests are damaged
